The amount of time for the above Internet activities will vary depending on participants' degree of interest in accessing the Internet resources provided. Approximately 1-4 hours per week or more will be needed to complete the Internet activities. Participants who are assigned to the intervention group who fail to respond to e-mail or to use any of the intervention resources for a one-week period will be contacted by telephone to determine the reason for not participating in the study activity (technical, knowledge deficit, medical, lack of ability, lack of interest, etc.).
